The audio device in sound panel is shown as disabled.
Can you send a screenshot?

Subject: [wdmaudiodev] Audio device lost after multiple cold boots
I am observing an issue during repeatedly cold booting the system over a long
period of time.
The audio device in sound panel is shown as disabled.
When I check the registry for the device under
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\MMDevices\Audio\Render\
"DeviceState"=dword:00000004
If I manually change the device state to 1, device is shown in control panel
again.
Also, if the audio service and audio endpoint builder service are stopped and
started again, the issue is gone.
Has anyone observed something similar.
I have checked that the driver is reporting the correct jack state to os when
queried
